Ebert has written a very good review on it, giving it a 4/4. The story being set in the year 2154 with James Cameron as the director, you wouldn't be disappointed I guess. It depends a lot on your taste in movies though. If you are not a Star Wars fan, you probably wouldn't like Avatar either 
Going to watch Up in the coming days

Up is great, a bit sad though. I loved Dug the speaking Dog
